BOTTLE-CAPPING MACHINE.

Application led December 29, 1921. Serial No. 525,645.

To all whom t may concer/n.'

Be it known that l, KENNETH H. KIEFER, a citizen of the United States, a resident of Baltimore and State of Maryland, have invented a certain new and useful Bottle-Capping Machine, of :which the following is a specification. y l

This invention relates to a bottle capping machine, and more particularly to machines designed to cap bottles by immersing their necks in coating solutions.

Although the invention may exist in various embodiments, a particular description of one kind of apparatus will be given below, this apparatus constituting a preferred embodiment. v p y This apparatus is illustrated in the drawings, which form part of this specification, and in said drawings. y l

Fig. 1 shows a side elevation of the apparatus;

Fig. 2 shows a side elevation-of the right endof the apparatus partly in section;

Fig. 3 shows a plan view of the right end of the apparatus;

Fig. et shows an end elevation partly in section showing a bottle dipping into the liquid used for coating; and

Fig. shows a similar'end elevation illustrating the bottle in withdrawn position.

Briefly described, the preferred embodlment consists of an endless belt mounted over pulleys set at lan angle to the vertical, the belt being provided with brackets for holding bottles, and a series of tanks is provided together with a camway contacting by suitable means with the bottle-holding means whereby the bottles are caused to descend into the tanks to be coated with the solution therein provided. i

By way of speciic description, and referring to Fig. 1, there are shown two pulleys 1 and 2 mounted uponaxles set lin bearings 3 and 4 respectively, which are positioned in standards 5 and 6. respectively, in such a manner that they occupy an oblique position, specifically 45"to the vertical. Between the pulleys, there are three tanks 7 8 and 9 constructed to contain liquids, tanks 7 and 8 being intended to contain a coating solution, whilel tank 9 contains water. Each of the tanks 7 andl 8 is provided with a separate circulation system in order tokeep'the liquid therein suitably agitated and consequently of homogeneous composition, and it will be necessary to describe only one circulation system, namely that of tank 7 This is best shown in Fig. 2, in which there is illustrated a pipel() posiltioned beneath the tank 7 and connected thereto by numerous small pipes 11, which conduct the liquid to the'pipe 10 and thence to a pump 12 which pumps the liquid yup through a pipe 13 back into the left end of the tank thereby completing the circulation.y

An endless belt 14 is mounted Vover the pulleys, and this belt has fastened at regular intervals along its outer surface a number of brackets 15 as shown in Fig. 2, between which-brackets the bottles to be filled are placed. rll`he bottles are indicated by the numeral 16, and they are enclosed within cylinders 17 whose lower ends are closed but have apertures to allow the necks of the bottles to protrude. The bottles are free to roll within the spaces between the brackets. The necks of the cylinders abut against camway 18 which has the same angle of inclination as the belt and pulleys, and which has depressed portions'adjacent the tanks in order that the bottles may descendv toward the tanks and have their necks immersed therein. These depressed portions are shown plainly in Figs. 1 and 2 land shown in sectional end view in Fig. 4. The tanksare positioned in operative relationship with respect to this camway so that the bottles will/1 descend to the required depth in the tanks .when the cylinders 17 roll down into the depressions in the ,camway A hood 19 is lbuilt on one side partlyover the tanks so that vapors of the coating solutions will not be lost but may be sucked into the hood and down pipes 20 into horizontal pipes 21, from which they pass through pipes 22 into a main pipe 23 which is connected through a pipe 24 to asuitable solvent recovery apparatus not shown.

The apparatus is operated from a suitable source of power connected to a driving pulley 25.-

'llhe operationwill be apparent from the above description and may be summarized as follows scend toward it by reason of the depression in the camway, thereby immersing the nec-k of the bottle into the liquid in the tank for a. suificient length of time to give the bottle one or two complete turns therein and thus give it an even coating. After the immersion, the camway again forces the bottle upward with its enclosing cylinder. The first two tanks beginning from the right end as shown in Fig. 1 contain coating solutions, while the tank-9 contains water to set and harden the coating on the neck of the bottle. The bottles are removed at the left end of the apparatus as shown in Fig. 1.

The angle of inclination of the camway, pulleys and connecting parts is preferably 45, but this an le may of course be varied. The cylinders 1t roll during the travel of the belt and thereby rotate the bottles so that they will receive a uniform coating.

2. Ina bottle capping machine the combination of a-transversely inclined conveyer for bottles to be capped. a stationary plate located alongside the lower side of the conveyer aga-inst. which the bottles -rest and whereby the bottles are caused to roll when the conveyer is moved, a tank yfor containing a coating liquid, said plate having means for -diI' (pi1`1g and withdrawing the bottles into an out `of the tank as the conveyer lis moved. v

:a 3. In a' bottle capping machine, the combination vof an endless belt mounted for travel-at an angle to the vertical, means thereon for holding bottles, 'a tank for containing liquids, andvmeans for dipping and withdrawing the bottles into and out ofthe tank comprising hollow rolling `cylinders and a cam on which the cylinders roll, said cam having depressions and elevations. 4. In a bottle capping machine, the comess belt mounted for belt, cylinders in the spaces between the brackets, said cylinders being constructed to hold bottles in an inverted position, a

tank for containing liquids, and a cam between the tank and belt in contact with the cylinders for dipping and withdrawing the bottles into and out of the tank.

5. In a bottle capping machine. the combination of an endless belt mounted at an angle over pulleys, partitions attached to and extending out from the surface of the. belt, a tank for containing liquids. and a camway in operative relation with the tank and belt, said camway having depressions and elevations to cause bottles placed on the belt to descend into and move out of the said tank.

6. In a bottle capping machine, the com bination of an endless belt mounted at an angle of about 45. brackets on the belt and cylinders between the brackets, a series of tanks and a camway in operative relation with the camway and belt. said camway having depressions and elevations to cause the cylinders to move towards and away from the tanks.

7. In a bottle capping machine. the combination of a tank for containing a coating liquid, means for dipping bottles into the tank, a circulation system for the liquid in the tank comprising conduits leading to a pumpmgmeansand a return conduit to the tank. and a vapor recovery hood connected to the tank to draw ofi' vapors from the i coating liquid.

8. In a bottle capping Amachine the combination of a transversely inclined conveyer for bottles to be' capped, said conveyer being provided with partitions extending therefrom for holding the bottles: a stationary plate located alongside the lower side of the conveyer against which the bottles rest and whereby the bott-les are caused to roll when the conveyer is moved: a tank for containing a coating liquid: said plate having means for dipping andl with rawing the bottles into and out of the tank as the conveyer is moved.
